We worked with Jacob for the mix and mastering of our first album 'Blackwaters' , what can I say? The reviews of our record says of him: 'The production is surgical and effective' ; 'The production is really good, giving the album a full sound that's also crisp and precise' 'an immense drum and guitar sound, with some tricksy mixing thrown in for good measure'...etc. etc. etc. So...what else to say? We are very pleased to have worked with him because he is a great professional and also knows how to always give the right way for your band!!!' - Ivan/Terrorway

“I have now worked with Jacob many times. Why? Because of the fact that he, besides making a great sound, also is easy to collaborate with. With a fair mix of patience and critical thinking he manages to get you to perform your best. And then he knows his stuff as a producer!” -Andreas Posselt

Jacob is very professional and dedicated. His approach to recording promotes a very encouraging and up-lifting atomsphere in the studio. Jacob has been impressively productive! He is fast and sharp behind the buttons. His approach to the whole process of recording is characterized by his general understanding of music. Jacob is not afraid of coming up with suggestions to improvements of the tracks. This constructive critique helps making the best of every track. We have been very pleased with the result of our recordings and we will definately recommend JBO-sound to every "serious" metal and rock bands - Magtesløs

We are very pleased with both the process and the result!! Jacob surely knows what he is doing and when we are booking a studio for our next record, mr. Olsen is the first one to call \m/
